Xorg issues on -current with Nvidia binary blob
First off, I realize this is not a standard Slackware installation, but maybe someone has an idea...
I killed my main work station by doing something that has worked 100 times before: I uninstalled the Nvidia driver, built a new kernel, upgraded some packages from -current, rebooted, re-installed the Nvidia driver.
The reason I did it: i wanted to stop log spamming caused by the current Nvidia driver 390.25.
Last time i did an upgrade of -current (minus the kernel build but including the nvidia cycle due to mesa being part of the upgrade) was 3 days ago. So the -current update gave me all the packages dated 2018-03-08 in the -current changelog for x86_64 (verified in /var/log/packages)
The issue is: when I start xorg, everything seems to start up correctly as far as I can tell from ps -Al. However, the monitors do not sync. I have verified it with the following combinations:
- a Philips 4K monitor and a Samsung Full HD monitor
- self-made kernels 4.14.24 and 4.15.7
- Nvidia drivers 390.25 and 384.98 (the latter compiles only on 4.14 with --no-unified-memory)
Is there maybe a package upgrade that might have led to this situation? Any ideas welcome.
